I have a 1293 with a 45 and its massivly overfuleing on idle anyone know what idle jet size it should ideally have as i'm not sure if they are wrong or if its another problem

[Bluemini]

According to the bible by Mr Vizard, you jets sizes should be as follows:

Standard Engine:
Choke..............35
Main Jet............150
Air Cor.............180
Emulsion Tube...F2
Pump Jet...........40
Idle..................50F2
Aux Vent...........4.5

Modded Head & Cam
Choke...............38
Main Jet.............165 - 170
Air Cor..............180
Emulsion Tube...F2
Pump Jet...........45
Idle..................50F2
Aux Vent...........4.5

These figures are for a 1275, because you've got a 1293, I'd be inclined to go for the latter set of figures...

cheers i'll have a look later. i'm assuming they are going to be nothing like those but i'm going to be using it on the road as before it was a tarmac rally car and spent a lot of time at 8k revs so i need a starting point to get it usable.
